Abstract
The invention discloses a method for preparing brown mica powder, and belongs to the field of methods for preparing mica. The method for preparing brown mica powder comprises the following steps: (1), material selection, (2), wet splitting, (3), rolling crushing, (4), screening and flotation, and (5) filtering and drying. For the brown mica powder, the granularity D50 is 10 <+/-2>(mum), the degree of whiteness is more than 60, the moisture is less than 1%, the PH value is 6 to 8, the bulk density is less than 0.17 g/cm<3>, the diameter-to-thickness ratio is more than 90; the content of heavy metals is as follows: Pb is less than 5, As is less than 1, Hg is ND, Cd is ND, Sb is ND, and Ni is ND. The method for preparing the brown mica powder has the advantages that the prepared brown mica powder has elasticity, remains the characteristics of sheet structure, large diameter-to-thickness ratio, high refractive index, high purity and high glossiness, and is fine in appearance, smooth in hand-feeling, and natural in color.
Description
Technical field
The present invention relates to mica preparation method field, be specifically related to a kind of phlogopite powder, preparation method thereof.
Background technology
Phlogopite is the one in white mica class mineral, belong to monoclinic crystal layer silicate mineral, it is a kind of aluminosilicate of iron content, magnesium and potassium, if the iron in phlogopite composition is not very many, it just can as electrically insulating material, and it is widely used in the chemical engineering industries such as building material industry, fire protection sector, fire-fighting medium, welding electrode, plastics, electrical isolation, papermaking, pitch paper, rubber, pearly pigment.
The phlogopite powder of fully natural green, can be directly used in muffin, BB frost, loose powder, foundation emulsion, facial mask etc. without the need to adding any pigment, receives the height praise of industry.
Phlogopite powder raw materials generally all selects phlogopite ore, and existing phlogopite powder finished product exists variable color, the shortcoming such as not meticulous.
Summary of the invention
The object of the present invention is to provide a kind of phlogopite powder, preparation method thereof, it is by artificial selection phlogopite ore, when ensureing raw ore solid colour, through wet method stripping, ultra-fine, classification, produces natural in human body complexion, phlogopite powder that silkiness is soft and smooth.
Technical solution problem of the present invention adopts following technical scheme:
A kind of phlogopite powder, preparation method thereof is provided, it is characterized in that its preparation method comprises the steps:
(1) selection: the natural high-quality phlogopite ore of artificial selection, density: 2.7-2.9g/cm
3whiteness: 60-70 transparency: 0-25.5%, specific refractory power: 1.6-1.55, Mohs' hardness: 2.78-2.85, coefficient of elasticity: 1394.5-1874(10 6Pa), the wherein transparent and tool vitreous luster of light phlogopite ore color, cleavage is pearliness;
(2) wet method stripping: the high-quality phlogopite ore of selection is adopted wet method stripping, by washing, removal of impurities, soaks, rolls and make sheet and just expect A;
(3) roll pulverizing: sheet is just expected A carries out cryodrying dehydration, and use wheel roller to roll, make phlogopite particle B and expect;
(4) flotation is sieved: by B material through screw classifier sieve classification, and floatingly select the fine material of phlogopite with flotation machine;
(5) filtering drying: the fine material of phlogopite of screening flotation is carried out filtering, dry and breaing up, obtains final phlogopite powder.
As preferred embodiment, described phlogopite powder: granularity D50 is 10 ± 2(μm);
